I think AO works like a champion with a big scope and an imperfect mount. I bought it more to fix tracking errors than for seeing issues.

Yes thanks Rick - Peter Ward pointed it out. It's worth a (very careful) read. Nice to see tech stuff peeking through the clouds of marketing hype. The main thing I took from it was that SBIG are aware that the currrent method of guiding on a single off axis star is not too good - hence their apparent intention to move to multiple stars, which will overcome the problem of noise injection into the guide channel.
Hi Peter. I agree that mount correction is where these things shine, not seeing correction, which is how they have been sold. Maybe there is a marketing problem - ie how do you sell something that fixes mount problems to people who believe that their mounts are perfect?
